Need be answer all four question a,b,c and d with well define and values are changes so please do not copy paste other answer.

Answer the following questions using the sensitivity report shown below. a) Report the optimal solution and the objective function. what is the range of optimality for coefficient of x? (4 marks) b) Report the range of feasibility associated with each constraint and Explain what constraints are binding and which one(s) are non-binding (5 marks) c) Will the optimal solution remain optimal if the coefficient of x changes to 7? Explain (1 marks) d) If the coefficient of x changes to 2 and the coefficient of y changes to 6 simultaneously, will the optimal solution remain optimal?
